Tropical Fish Upside Down Catfish

Has anyone successfully raised catfish upside?

I have one gallon tank with a variety of 55 tropical fish (guppies, platys, tetras, etc.) I have two catfish in reverse too, and now one of them is bad throughout the year. I have successfully bred guppies and platys but they were all live births. So if I put a boat in the reservoir and pond eggs in other fish eat them or "I can transfer the eggs into another tank?

Yes, it's done. But not common. The Most sources say that lay their eggs in a depression in the gravel, but 1 source said I found that the eggs in a piece of PVC pipe. Other species of Synodontis are generated in clay pots as some cichlids, and even some mud houses that are only for spawning synodontids, so that could be that the fish that spawn in gravel simply not the right type of coverage the beginning of their eggs. Maybe some PVC or clay in a pot, and the elimination of other fish not to eat fish eggs is all his needs. You can make a mud cave for spawning if you use pottery dish and a hole at halftime tires big enough for fish to enter, then turn this upside down in your tank.
